Personally, i am not very in favour of this rule. To begin, i don't find it necessary to have such rule applied, since i don't find a reason for event hats to become more rare and there has always been a time when you lose the warp or seen the message too late to even stand a chance, so a second or even third chance is great. Also, as mentioned before, i personally live in a time zone when not many events happen, so way minimize my possibilities to participate in an event?
These are my thoughts over this topic
